I REFRIGERATOR LUNCH-BOX.

SPECIFICATION forming part Of Letters Patent No. 601,798, dated April 5,1898.

. Application filed May 4, 1897. $erial No. 635,002. (1% model.)

To all whom it may concern.-

Be it known that I, ADOLF SLOMKA,a citizen of the United States,residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Refrigerator Lunch-Boxes, ofwhich the following is a specification.

This invention relates to-a lunch-box for general use, but one which isespecially well adapted for use at picnics and outings and forbicycle-riders and travelers. The box is adapted for ice for keeping thecontents of the box cool.

The special features of the invention are illustrated in theaccompanying drawings, which show an embodiment thereof.

In the drawings, Figure 1 is a perspective view of the lunch-box as itappears when the cover is omitted, and Fig. 2 is a longitudinal verticalsection of the same with the cover in position thereon. Fig. 3 shows thesuspended tray detached. Fig. 4 is a perspective view showing thelunch-box adapted for attachment to a bicycle.

Referring to the first two figures, which show the lunch-box asconstructed for general use, 1 represents an outer box constructed of asubstantially waterproof paper-board, which is well known in the market.This outer box is made by cutting the material to a pattern withsuitable overlapping flaps, which are secured by rivets. Within theouter box 1 is tightly fitted a sheet-metal box 2, which projectssomewhat above the outer box. The box-cover is made in a similar way. Itconsists of an outer cover 1 of Waterproof paperboard and an inner cover2 of sheet metal. The sheet metal will be by preference tinplate or zincbut it may be aluminium. This metal may be quite thin and light, as theouter covering of paper-board serves to reinforce it and add strength.

In order to secure the cover removably on the box, straps are provided,as will be described. A leather strap 3 is secured to the bottom and endof the box by rivets 4., which extend through both the outer and innerboxes and secure them together. This strap 3 extends over the top of thecover, Fig. 2, and is secured thereto in the same manner by rivets P, soas to form a hinge for the cover. In Fig. 1 the strap 3 is representedas broken across at the hinge-point, as the cover is omitted from thisView. On the opposite end of the box, at the right in Fig. 2, there is astrap 5, secured to the box in the same manner as the strap 3; but it isprovided at its upper end with a buckle 6, to be secured to a strap 5 onthe cover.

On the cover is ahandle 7. (Seen in Fig. 2.)

Within the inner box 2 is atransverse fixed partition 8, which extendsfrom the bottom of the box nearly to its top. This partition has in itnumerous apertures 8 and it divides the box into two unequalcompartments a; and

w The lesser compartment 00 contains a can or vessel 9, which fits quitesnugly into the compartment and has a cover 10. The larger compartment'00 is divided horizontally by a suspended tray into an ice-chamber,marked Ice in Fig. 2, which is below the tray, and a food-chamber,marked Food above the tray. The tray 11 has in it numerous apertures, asclearly shown in Fig. 3, and has at each of its ends a sheet-metalsuspendinghook 11 one hook being adapted to take over the end of themetal-box 2 and the other over the partition. This tray supports thefood. The hook 11 which is adjacent to the partition, may be apertured,as seen in Fig. 3, to allow the cold air to flow freely to the vessel inthe lesser compartment.

In the end of the box is a stoppered outlet 13, Fig. 2, for the waterfrom the molten ice. Fig. 4: ShOWS the lunch-box adapted to fit into theframe of a bicycle. Interiorly this box will be constructed and arrangedsubstantially in the same manner as has already been described, andexteriorly it will have similar straps for securing the cover; but inlieu of a handle it will have straps 14, for securing it to the bars ofthe bicycle-frame. This box may have a handle also, if desired; butordinarily a handle will not be required. The invention is not limitedto any special size or proportion of the box nor to any particular metalfor the interior. The box will be found very useful for any occasionwhere the contents of the box are to be kept cool. The outer box beingof a material which does not readily conduct heat will enable the ice tobe kept for a considerable time.

Thev material of the outer casing of the box and its cover, which hasbeen called paper partments, and an outlet for the water from the ice, asheet-metal cover for said box, said cover being also covered withwaterproof paper-board, a hinging-strap 3, which hinges the cover to thebox, a securing strap and buckle for said cover, and an apertured tray11, suspended in the box over the ice-chamber, said tray having hooks 11which take, one over the partition in the box and the other over one endof the latter, substantially as set forth.

In witness whereof I have hereunto signed my name in thepresence of twosubscribing witnesses.

ADOLF SLOMKA.
